Currently I'm stuck with an Archlinux system at work. However, I want to be able to package some software for Ubuntu on this machine. So I thought it should be possible to set up an Ubuntu (Precise) system inside a chroot environment on my Archlinux box. Of course, I wouldn't have X11 in the chroot, but I wouldn't need that.

Any thoughts on how I can install Ubuntu inside a chroot environment on my box?
